Title: Method and apparatus for measuring fiber orientation distribution
Inventor: SEKINE HIDEKI
IPC: G01N21/89
Filed: 1995-03-07
Abstract: PURPOSE: To improve a measuring accuracy of a fiber orientation distribution by acquiring a parameter indicating a feature of a fiber orientation distribution based on a projection image of a fiber to be measured as photographed from a plurality of directions. CONSTITUTION: A plurality of X-ray films which image a sample are read by a camera 1 and a CPU 10 of an image analyzer 2 calculates a fiber projection area in images to determine the proportion of the area for the total. A value L defined by the formula is calculated based on an area value in calculation determined by the proportion of the area and an arbitrary parameter value. Then, a parameter value is altered sequentially to determine the value L and when the minimum value thus far obtained is larger than the value L obtained, the value L is set to the new minimum value. This parameter value is preserved. In this manner, the parameter value is altered to the final set value varying the value, while the minimum value is updated. Thus, the parameter value corresponding to the minimum value left last is obtained as solution to the minimization problem.  The value obtained is used to calculate the orientation distribution of fibers.

CONSTITUTION:When a fuel oil is supplied to a combustion apparatus 2 by a supplying pump 3, the pressure of the oil is maintained to be constant by a high-pressure pressure control valve 7, whereas the pressure on the outlet side of a fluid controller 5 is maintained to be constant by a low-pressure pressure control valve 8. When the viscosity of the fuel oil is increased, the flow rate of a flow through the fluid controller 5 is reduced, the opening of the pressure control valve 8 is reduced, and a signal of the changed opening of the valve 8 is sent to a vapor control valve 10 to increase the quantity of a vapor fed to a feeding heater 4, thereby raising the temperature of the fuel oil. The viscosity of the fuel oil is decreased, the quantity of the oil is increased, and the opening of the valve 8 is returned to an initial value. When the viscosity of the fuel oil is deceased, an operation opposite to the above is conducted. By this, the fuel oil with constantly fixed viscosity is supplied to the combustion apparatus 2.

IPC: H04N5/18
Filed: 1982-03-26
Abstract: PURPOSE:To reduce the level variation of a DC reproduced output signal due to an excessive change of the reference level, by replacing the DC reproduced output signal with an original signal, i.e., an input signal when the reference level of the original signal exceeds the prescribed width of variation. CONSTITUTION:When an original signal 1 is supplied to an input terminal, a signal 6 obtained by DC reproducing the reference voltage to the reference level voltage Vref is delivered. In this case, the impulsive noise is superposed on the part of a reference level signal to cause a significant change to the reference level. As a result, the DC level of the signal 6 varies. While comparators 24 and 25 and an exclusive OR26 form a circuit which detects that an input signal, i.e., the original signal has exceeded the changing width of the reference level. Now the signal 6 is replaced with the original signal, i.e., an input signal 1 when the reference level of the original signal exceeds the prescribed width of variations with the timing of the pulse of the output 5 of a one-shot nulti 17. As a result, it is possible to reduce the level change of the signal 6 due to an excessive change of the reference level.

Title: Adjuster cylinder control circuit for working machine with crawler belt
Inventor: TAKAHASHI TOSHIAKI
IPC: B62D55/30
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To appropriately absorb the stroke fluctuation quantity in either case of load being applied to both adjuster cylinders or to only one adjuster cylinder. SOLUTION: An accumulator 13 is connected to piping 12 which connects each oil chamber 9c, and an accumulator 14 is connected to a feed oil path 18 branched from the piping 12, through a selector valve 19. Lateral ports of the selector valve 19 are respectively connected to the oil chambers 9c. When large load is applied to both adjuster cylinders 11, since the accumulator 14 is connected to the feed oil path 18 through the selector valve 19, pressure oil discharged from the respective oil chambers 9c is absorbed by two accumulators. When large load is applied to only one adjuster cylinder 11, the accumulator 14 is cut off from the feed oil path 18 by the actuation of the selector valve 19, so that the pressure oil is absorbed by only the accumulator 13.
